To all whom it may concern:

Be it known that I, PATRICK 1VIAGENNIS,Of Paterson, in the county of Passaic and State of N ew J ersey,havc discovered a new and useful Improvement in the Art of Dyeing; and I do hereby declare that the following is a full and exact description of said improvement.

The nature of my improvement consists in performing the operation of dyeing by one process, which is efiectedin the following manner: The cloth or other material-to be dyed is taken, without any previous preparation, and passed through the vessel or box containing the coloring-matter, and from thence immediately passes between heavy rollers or squeezers, whereby the coloring matter is effectually forced into the cloth or other material. It is then dried, and being so dried it is passed through thevessel or box containing the proper mordant, and from thence again immediately passed between heavy rollers or squeeznrs,

What I claim as mydiscovery andinvention,

and desire to secure by Letters Patent, is?

The mannerof applying the'coloring-matter and mordants in a concentrated state to the dry cloth or other material to be dyed by passing the same between rollers.
